Bar Italia has always been my regular go-to place for when we are looking for a casual meal. The caf style atmosphere and the friendly staff are just some of the things that keep me coming back. They also have plenty of indoor seats and spacious outdoor courtyard that are perfect for a relaxed dining experience, although you might have to deal with the airplane noise once every 5 minutes.
There are great ranges of pasta with variety of sauces available, as well as other main meals such as veal. The pasta meals are quite nice and are adequately portioned considering the price (which is quite of a premium range given the atmosphere). Then they also have the delicious home-made gelato that everyone should at least try once they are of generous serving size. Dont go past the tiramisu, which is of the favourite of many. Sadly enough, this place is not as busy as it used to be.
